Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction moulds, and specifically relates to a mould shell structure. Background Art

[0002] Formwork is a construction tool for cast-in-place concrete, mainly plate-type components. The main process of formwork construction is usually to set up the full frame - lay the wood - install the frame beam formwork - lay the rib beam bottom formwork - tie the frame beam reinforcement - draw the rib beam center line - fix the formwork - tie the rib beam and floor slab reinforcement - pour concrete.

[0003] Quality problems caused by mold bursting and mold running during concrete pouring will cause difficulties in the decoration stage. In order to deal with mold running, fasteners are usually used to fix the folded edge of the mold shell to the bottom support plate and anti-floating steel bars are set on the top of the mold shell.

[0004] The problem with the existing technology is that the installation and positioning of the formwork are complicated; the formwork is fixed to the support plate with fasteners or anti-floating steel bars are set to prevent the formwork from floating, which is complicated to operate. The use of fasteners is not convenient for disassembly of the formwork, and the setting of anti-floating steel bars usually requires additional pads to ensure the thickness of the steel bar protective layer; the formwork structure is not strong enough and is easily damaged, affecting its use. Summary of the invention

[0005] The utility model aims to provide a formwork structure for the problems existing in the prior art, which has the advantages of convenient construction, simple assembly and disassembly, and convenient use.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a mold shell structure, including a shell body, the shell body includes a top plate, the bottom surface of the top plate is provided with an annular side plate along the outer circle, the bottom of the annular side plate is inclined outward to form a draft angle, the bottom of the annular side plate is formed with an outward folding plate, the bottom inner circle of the folding plate is formed with a positioning protrusion for cooperating with the bottom support, the top plate and the annular side plate form an inner cavity opening facing downward, the inner surfaces of the top plate and the annular side plate are provided with a plurality of reinforcing ribs, the inner surface of the annular side plate is provided with a handle, the bottom surface of the top plate is provided with a mounting component, the mounting component is formed with a hanging portion, and the hanging portion is used for detachably connecting anti-floating weights.

[0007] In the above solution, a shell main body that bulges upward is formed by the top plate and the annular side plate, which is convenient to be used as a bottom mold during the construction of building concrete pouring. The outward inclination of the annular side plate is convenient for detaching the shell main body from the concrete building downward after the building structure is stable. The flanging plate at the bottom of the annular side plate is used to fit the top surface of the bottom support under the action of the weight of the upper concrete to prevent leakage during concrete pouring. The positioning protrusion at the bottom of the flanging plate is used to cooperate with the bottom support for positioning to prevent the shell main body from shifting horizontally during concrete pouring and vibration. The top plate and the annular side plate form an inner cavity, making the structure simple and saving materials. Reinforcing ribs are provided to strengthen the shell main body to prevent the structure from cracking or breaking due to compression or impact. Handles are provided on the inner surface of the annular side plate, which is convenient to move the shell main body through the handles and apply a downward pulling force to the shell main body during demoulding, eliminating the need to use a crowbar tool and avoiding damage to the flanging plate, with convenient operation. Mounting members are provided on the bottom surface of the top plate, and anti-floating weights are suspended through the hanging portions, thereby preventing the shell main body from floating during the concrete pouring process.

[0008] Further, the mounting member includes a plurality of connecting rods. The tops of the connecting rods are evenly distributed on the outer circle of the bottom surface of the top plate, and the bottoms of the connecting rods are connected directly below the center of the top plate.

[0012] Further, the top plate is a circular plate or a rectangular plate, the annular side plate is an arc-shaped plate or a straight plate, and the thicknesses of the top plate and the annular side plate are equal.

[0013] The top plate can be set as a circular plate or a rectangular plate, and a variety of cavity structures for the building bottom surface are formed in cooperation with the corresponding annular side plates. Setting the circular plate structure is beneficial to avoiding stress concentration at the corners of the top plate.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The shell body is positioned horizontally by setting a positioning protrusion at the bottom of the folding plate to cooperate with the bottom support. There is no need to set additional horizontal limit pads. The anti-floating weights can be detachably set on the installation components of the inner cavity to prevent the shell body from floating during concrete construction. The structure is simple and the positioning and installation construction are convenient.

[0020] 2. The bottom support is engaged with the positioning protrusion and the anti-floating weight is used to ensure the positioning of the shell body. No fasteners are required. After the concrete structure is stable, it is convenient to separate and disassemble the shell body from the bottom support. There is no need to destroy the bottom support. The bottom support and the shell body can be reused, saving costs.

[0021] 3. The structural stability is ensured by setting reinforcing ribs in the shell body to avoid damage to the formwork shell and affect the concrete structure.
